With only one film credit to date—she played Maid #3 in The Dark Knight Rises—Claire Julien makes her breakout turn in **Sofia Coppola’**sThe Bling Ring, about a group of celebrity-obsessed teenagers who go on a star-studded heist, which premiered at Cannes and opens in New York and L.A. this Friday. The 18-year-old actress (and future student at Los Angeles’s Fashion Institute of Design & Merchandising) talks to Vogue.com about dining with Peter Dundas, watching herself onscreen, and filming in **Paris Hilton’**s house.

Where are you this morning?I’m at the airport with my mom, buying magazines, about to head back to LA. We’ve been in New York since Monday night, went to the premiere on Tuesday, and had dinner last night at Omar’s with Peter Dundas. I wore Pucci, obviously—a baby blue dress that looked like it was out of Alice in Wonderland.

Was that the first time you’d met Peter Dundas?I first met Peter in Cannes, where I wore one of his dresses, but it was amazing to talk to him last night about his new resort collection, which is all relaxed and beachy. I love his colors and that he decided to use denim. It feels very California.

How did you find New York?This whole trip was a little melancholy, actually. It was the last hurrah with Sofia and the cast. I hope to see Israel [Broussard] soon because he’s half based in LA, but Taissa [Farmiga] is in New Jersey and filming American Horror Story in New Orleans, Katie [Chang] is going to Columbia [University] in the fall, and Emma [Watson] is all over the world. So this was kind of the end.

What’s the first thing you’re going to do when you get back to L.A.?Shower! I can’t stand planes and airports.

Your dad is the Oscar-winning cinematographer Wally Pfister. What was it like to play a character on the outside looking in?Well, my father’s success has just come about in the past few years, really, and because he’s behind the camera we don’t have to deal with the celebrity side of it. But I do think it’s interesting that Sofia made a movie like this, because it’s pretty close to home for her. And I also think that’s why it was so important for her to make it. She felt like it was a story that needed to be heard and wanted to make a statement about the unhealthy obsession with celebrity.

What was it like to watch yourself onscreen?Fine, fine. There is the one horrible moment, though, where the group comes back from robbing **Rachel Bilson’**s house and I say, “Look at their chill-ass Chanel purses, dude,” and then give this terrible laugh. It makes me cringe! I have the worst laugh I’ve ever heard, anyway, but this was unbearable.

When we first saw the movie together a couple of months ago, you told me that you thought it glorified what these kids did. Do you still think that’s the case?Well, it’s definitely a cautionary tale. My worry initially was that people would interpret it as a glamorization of what they were doing, but really Sofia conveys the danger of how far celebrity culture has gone. It’s ironic being a new actress, and especially for Emma, to portray this world. We’re making this statement about celebrity and then going to all these premieres and photo shoots and Cannes.

In the end, it’s still a big Hollywood movie.Exactly.

To add to the irony, you shot in Paris Hilton’s actual home. What was that like?It was a surreal experience. And it’s not because we’re into her as a celebrity. It’s just weird! Her house is an entirely different world. It isn’t Earth; it’s an entirely different planet. Seeing how she lives her life and how her home looks really brought us into the mindset of these characters because that was the house where the actual robberies took place. We had fun there, too. Most of the time when we weren’t filming, Taissa and I were outside playing soccer with the security guards.
